Question

Explain vector and kinematics​

Answer 1

Answer:

The speed | v | mentioned in the previous chapter is the magnitude of the velocity vector  v ; v is the component of the velocity along the trajectory, which can be either positive or negative. When vectors are used to describe the motion,  v and  a are simply called velocity and acceleration

Answer 2

Answer:

Kinematics is a subfield of classical mechanics that describes the motion of points, bodies, and systems of bodies without considering the forces that cause them to move. Kinematics, as a field of study, is often referred to as the "geometry of motion" and is occasionally seen as a branch of mathematics.
